Tiredness at twenty weeks of pregnancy

Sleep disruption, not eating or drinking enough, stress and the body's increased workload may all reduce energy. Anaemia is another relevant cause during pregnancy, particularly when tiredness comes with breathlessness, palpitations, dizziness, headaches or pale skin.

Energy varies between pregnancies and from day to day, so compare the symptom with your own usual function. Note whether you can recover after rest, whether sleep is refreshing, and whether fatigue started suddenly or is steadily increasing.

Anaemia commonly presents with low energy and may also cause a racing heart or shortness of breath. Dehydration can present with tiredness alongside thirst, dark urine, headache or light-headedness. Infection, thyroid problems, low mood and other medical conditions can produce similar symptoms, so persistent fatigue is not diagnosed from tiredness alone.

Pace demanding activities, build in short rests and keep a consistent sleep routine. Drink regularly and eat balanced meals containing protein and iron-rich foods. Gentle activity such as walking may improve sleep and stamina when your maternity team has not advised restrictions.

Mention ongoing fatigue at your antenatal appointment. Your clinician can review diet, sleep, mood, medicines and other symptoms, then decide whether blood tests are appropriate. Take iron only as advised because the correct plan depends on your results and iron can cause digestive side effects.

Seek prompt assessment if tiredness is sudden, severe, worsening, or paired with fainting, persistent dizziness, palpitations, fever, breathlessness at rest, chest pain, inability to keep fluids down or much less urine than usual.

Contact your maternity unit urgently for heavy bleeding, severe abdominal pain, a strong headache with vision changes, sudden swelling, or feeling acutely unwell. If low mood, hopelessness or anxiety is affecting daily life, tell a healthcare professional; seek emergency help if you may harm yourself.

Ask whether your fatigue pattern warrants a blood count or another check, and whether your prenatal supplement contains what you need. Describe sleep quality, diet, fluid intake, mood, exercise tolerance, dizziness, breathlessness and any change from your normal activities.
